Chancing the RTCSessionDescription.sdp ?

[fanno]

How do i change the value of this ? speseficly i want to change the m= parameter i want to change it curently it is:
m=application 9 UDP/DTLS/SCTP webrtc-datachannel

i want to change this to something that makes sence i cant figure out where this comes from "UDP/DTLS/SCTP webrtc-datachannel" i figure is due to it beeing a data channel but the application 9 is "nonsence" and if somone else ahve the same "autogenerate" name it would intefeer with mine would it not ?

i want it to be something like:
m=myAppName {UUID} UDP/DTLS/SCTP webrtc-datachannel

Where uuid is a "secret" that that client 1 knows and client 2 has to enter it in order to be able to "connect"

I do not see anydocumentation about wher ethis comes from.

can anyone help ?
